To all whom it ma/y concern:

Be'it known that we,MoUmJnn W. Cowan and DAVID -Fnurnn, citizens of theUnited States, residing at Parsons, in the county ot 5 Labetteand Stateof Kansas, have invented new and useful Improvements in Oil-Burn- .ersof which the iollowing is a specification.

.lhis 'inventionvrelates to improvements in crude oil burners adaptedfor use in heating stoves and also for use in the furnaces of steamboilers and for other analogous purposes, the object of the inventionbeing to provide a novel form of burner which is not liable tobe'comeclogged with" the oil when the vapor thereby etiecting a completecomhustion o the oil and producing no smoke.

-With these and other objects in view, the

, invention consists in the construction, com- 20 bination and arm ementof devices hereinafterdescribed an claimed.

The accompanying drawing is a sectional view of a crude oil burnerconstructed in accurdunce with our invention, showin forming a casing.

In accordance with our invention, weprovide a downwardly extending airmlet and heating chamber which in t e embodiment of the invention hereshown is open at its lower and, is provided at its upper end with alaterally "indie cy indrical m'form. The said cham ber may have itswalls constructed of any suitablematet'ial such as iron or steel and inpractice, is dis need in an outer casing which is here in icated as thecasing 3 of'a heating stove. The intake arm 2 of the said chamber 1extends and is attached to one side ofthe outer casing 3 as at 4 andcommunicates with an air intake opening 5, whichmay be opened or closedto any de-. sired extent-by a valve or'draft device 6. Thestove isshownasprovided near its uppefndmith an inclined ballle j and with apipe 8. In the. lowerportion offlqi ave 15 a pan 9, corresponding withan its pan, and above the same 1s a'basin shaped nettin 10 in whichignited materialitnay be 1 1 art the'burner in operation. The said nettj is here shown assup ported onone side bracket ilggndon t e oppositeside by an arm 12,. mgyifsuitable snippet-ting means n is l empl y The$111 posed i it 1 which vaporizes the oiliand burns the same for use ina heating stove, the atter;

inclined intake arm or portion 2 for the purpose of gcn'eratingheat to vthe chamber 1. The, stove is provided with the usual door 13 to enablethe pan 9 to be placed in or removed therefrom and with the usual door14 corresponding with a tire door, the same being located at such pointas tion of the chamber 1 readily accessible.

In chamber 1 is a vaporizer 15 which here shown as bell shaped orconical, is open a't its lower end and is provided near its -lowe'r endwith a series of openings 16 to 'admitair to. the interior of thevaporizer from the chamber 1. The retort is here shown as formed .at its11 per end with a cylindrical portion 17 to which connected tie lowerend of an oil feed pi 3c 18 having a bore of suitable diameter, the saidpipe being disposed in an upright position and in practiceleadingdownwardly from a suit able reservoir or vessel containing crudeoil. Inpractice, a suitable valve will be emgloyed to re ulate the flowof crude oil ownwardly t irough the feed pipe 18 to the hell orvaporizer. It will be observed that the lower end of the oil feed ipeterminates rizer. In practice the flow of 'oil through the pipe is socontrolled by the valve that the oil is'caused to pass slowly throughthe pipe and in a small quantity so that the oil s reads on the innersurface of the i e and a so 51 eads on the inner surface ot tlie hell orvaporizer, hence, the interior surface of the wall of the bell-shapedvaporizer is supplied with oil continuously by the said ipe. Assuminthat the hell or vaporizer has een. initially eated to the requisitedegree, the crude oil as it comes downwardly throu h the pipe 18 will beconverted into as in t c retort both by direct contact with t e heatedinterior surface of the vaporizer and by the heat reflected therefrom.The air in descndih through the chamber 1 will be heated oth by thewalls of said chamber and by'the eaterior of the heated vaporizer andhence the air which enters the vaporizer atrthe lower open end thereofthrough the openings 16 from the chamber 1 will be heated and willcommingle with the heated ases or. vapors from the vaporizer and "once"such eommi led air and sees or vapoi's'w ill burn be ow the vaporizerand in thecasingB, as will be understood. The 'prodticts of combustionpass off through the draft pipe 8. The pan 9 serves to receive octand;other unconsumed particles which to render the netting l0 andthelower porin the upper end of the bellshaped vapodro from the burner andinterior "a rface of tlie easing and permits the read removal of suchparticles.

Owing 'to the fact that the retort is at the lower end of the feed pipeand that the oil passes downwardly through said feed pipe to thevaporizer, the oil is efiectually prevented from clogging up the feedpipe and its flow to the va )onzer is uninterrupted while the controling valve of the said pipe is open. water, if any in the oil, will noteffect the operation of the burner but will be vaporized and its vaporwill eomrningle with the vapors or gases from the oil and with theheated air in the va )0 rizer and combustion will uninterruptec 1yproceed.

It will be obvious that our burner may be l A crude oil burnercomprising a casing.

In testimony whereof we aflix our sigma tures i, prsenee of twowitnesses.
